针刺百会水沟神门影响血管性痴呆患者脑区血流量的观察

目的:运用单光子发射型计算机断层显像(SPECT)技术,观察针刺百会、水沟、神门对血管性痴呆(VD)患者不同脑区血流状态的影响。方法:10例VD病人,随机分为2组。对照组治以针对偏瘫的常规穴位(手足三阳经为主),治疗组加用百会、水沟、神门。治疗前后,所有病人均接受SPECT检测。划定VD患者双侧额叶(眶回)、双侧顶叶、双侧颞叶(海马及海马旁回)、双侧枕叶、双侧基底节区、双侧小脑为感兴趣区。分析各区血流状态,并进行治疗前后的比较。结果:对照组患者治疗后,健脑基底节区的血流量显著升高;治疗组患者治疗后,双侧额叶、双侧顶叶、健脑颞叶、双侧枕叶、双侧基底节区、健脑小脑的血流量升高具有统计学意义。结论:初步表明百会、水沟、神门治疗VD的机制,与其改善脑区血流状态有关。

Effects of Needling in Baihui,Shuigou and Shenmen on Regional Cerebral Blood Flow in Vascular Dementia Patients

Objective: To observe the effect of needling in Baihui(DU20),Shuigou(DU26) and Shenmen(HT7) on regional cerebral blood flow in vascular dementia(VD) patients by single photon emission computed tomography(SPECT).Methods: Ten patients suffered from VD were divided into 2 groups randomly.Patients in group A received the treatment of needling in the routine Acu-points for hemiplegia(Acu-points were chose from 6 Yang meridians of hand and foot),while patients in group B received the treatment of adding 3 Acu-points,Baihui(DU20),Shuigou(DU26) and Shenmen(HT7),which were specially for treating dementia.All the patients were examined by SPECT in order to detect the cerebral blood flow of bilateral frontal lobes,temporal lobes,parietal lobes,occipital lobes,basal ganglions and cerebellum before and after treatment.Then the results were compared in statistics way.Results: Blood flow in bilateral frontal lobes,temporal lobes,parietal lobes,occipital lobes,basal ganglions and cerebellum of light affected side increased obviously in group B,but the increase happened only in basal ganglion of the light affected side in group A after treatment.Conclusion: Needling in Baihui(DU20),Shuigou(DU26) and Shenmen(HT7) can specially act on the cerebral blood flow of vascular dementia patients and improve the regional blood flow.
